Another quarter, another rise in US out-of-home (OOH) ad spending. This time OOH ad revenues grew by 3.8% year-over-year during the third quarter, per the Outdoor Advertising Association of America (OAAA), as the sector continues to roll on for closing in on a decade now without a single quarter of decline. For the year-to-date, industry spend is up by 3.7%.

Notably, the OAAA revealed figures on digital’s position within the broader OOH advertising industry, indicating that digital out-of-home represented more than one-quarter (28%) of the total during this past quarter.

That’s a considerably lower percentage than estimated by PwC earlier this year, though. In its forecast, PwC tallied digital at 40.7% of total US OOH ad spending this year, with that figure expected to grow to 47.9% share in 2022 on the back of a higher 2017-2022 compound annual growth rate than physical OOH (8% and 0.4%, respectively).

PwC’s forecast implies that virtually all growth in the US out-of-home advertising sector will come from digital rather than physical OOH. A recent forecast from Warc arrives at a similar conclusion, calling for digital to account for all of OOH’s growth on a global basis from this year through 2021.

Warc’s forecast sees digital out-of-home ad spending increasing by 10.1% each year between 2018 and 2021. Digital is expected to occupy 37.3% of worldwide OOH spending this year, up from 34.8% last year, less than one-third (32.4%) in 2016 and less than one-quarter (22.7%) in 2012.

Tech Brands Up Spend

Results from the third quarter suggest that tech brands remain invested in out-of-home. Apple was the second-largest advertiser by total spend, behind only Geico, while Amazon (to the extent that it’s considered a tech, rather than retail brand) was the 5th largest. Moreover, the OAAA notes that 14 tech brands increased their spend by double-digits year-over-year, including Amazon, Facebook, Microsoft, Netflix, Oculus, and YouTube.

In terms of industries:

The Miscellaneous Services & Amusements sector was by far the largest industry spender in Q3, accounting for almost one-quarter (23.2%) of total spend, including a 7.5% increase in investment year-over-year;

The Government, Politics & Organizations industry was the fastest-riser among the top 10 in terms of spending, with the 16.2% year-over-year increase likely a result of political advertising for the midterm elections;

The Insurance and Real Estate sector also hiked its spend by a considerable amount, with a 15.6% rise year-over-year; while

The Restaurant (-12.2%) and Automotive Deals & Services (-6.1%) sectors were the only among the top 10 to have a decrease in spend.
